Automatic Power Control for Higher Safety in Laser Diodes
Laser Components USA, Inc. Posted 11/07/2017
In Case of Danger, the Laser Diode Shuts Off
The new A4 series of compact APC laser diodes offers additional protection for whenever an eye-safe radiation beam is required: As soon as the operating current exceeds a certain level, the automatic power control (APC) shuts down the laser diode.
The A4 laser diodes are insensitive to electrostatic discharges of up to 10 kV and guarantee a stable output power at supply voltages of 2.5 to 6.0 VDC. As in its predecessor, the control is located at an ASIC on the same chip as the photodiode and the emitting laser diode, and it is integrated in compact TO housings (3.3 mm or 5.6 mm). These laser diodes are available in different wavelengths between 635 nm and 850 nm.
The A4 APC laser diodes are available at LASER COMPONENTS. They are used, for example, in high-precision measuring devices.
